MEAgURlNG DEVICE.

Application 'filed September This invention relates to improvements in measuring devices and more particularly to such as are adapted for use in measuring the depth of oil, gas or drilled or partly drilled wells,the object of the invention being to provide simple means which maybe readily placed in posit-ion and supported over the mouth of a well in such relation to the ropeor cable which carries the bailer or other weight, that the depth of the well may be accurately measured during the upward or downward movement of said rope or cable.

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in th :laim. I

In the accompanying drawings, Figure 1 is a view in elevation showingmy improved device in position over the mouth of a well and illustrating its relation to the rope or cable. Figure 2 is a sectional view, and Figure 3 is aview showing the tension block and adjusting means 1 there- The device embodying my invention com-- pr ses two frame members H separated from each other by a suitable spacing block 7 and at one end, by a block 5 conforming in shape to the approximately triangular shape of the frame at this end. The angular block 5 is removably secured in place in the frame by means of screws or bolts 6 and through i this block, a screw 7 is threaded and connected at one end with atension block 8 through the medium of arch-springs 9, the

other or free end ofsaid screw being provided with a suitable handle 10 for manipulating it. Bars 11 are secured at their respective ends to the frame members 4-4: respectively and between these bars. grooved wheels 12-12 and 13 are mounted in position to engage the rope or, cable 3. The tension' block 8 carries grooved rollers 14: which are so positioned as to bear against the rope 20, 1921. Serial No. 501,918.

or cable 3 between the grooved Wheels 12 and 13 and in proximity to the former.

In order to permit the application of the device to the rope or cable, it is necessary to first remove the block 5 together with the tension block 8 and adjusting screw? and after the device shall have been applied to the rope or'cable, these parts will be replaced.

uated in, inches. Theshaft 16 to which the intermediate wheel 13 is secured, is provided in its end, or rather in each end, with a notch 17, in Which the driving member 18 of a register 19 enters. This register may be supported through the medium of suitable attaching means to one or the other of the cross-bars 11.

applied to the rope or cable 3 by manipulating the screw 7 and that the grooved wheels 14 of the tension bar 8 will so engage the rope or cable as to insure accurate co- The intermediate grooved wheel 13 is pro vlded on each of its faces with-a scale grad- It is apparent that suitable tension may be operation of the intermediate wheel 13 therea a I with so that as the cable moves up or down the wheel 13 will be rotated so as to denote the number of inches traveled by the cable until the latter has moved one foot and then the co-operation of the wheel shaft 16 with the driving member of the register will cause the latter to register one foot and these op-- erations will be repeated throughout the length of travel of the cable from end to end of the well and the depth of the well will be indicated on the register.

In Figure 1 of the drawing I have shown I the register so disposed that the depth of the well will be indicated thereon during the upward travel of the rope or cable. To adapt the device for measuring the depth of the well during the downward travel of the I rope or cable, the register will be placed at thev opposite side of the device so that its driving member will engage in the notch at the other end of the wheel shaft 16'.

Having'fullydescribed my invention what I claim. as new and desire to secure by Let ters-Patent, is:
